research room is a novel environment - researchers were behind a two-way mirror
infant's behaviour tested in presence of a stranger and separation from caregiver
infant's behaviour recorded every 15 s
Ainsworth aimed to investigate:
Infant's willingness to explore
Stranger anxiety
Separation anxiety
Reunion behaviour
Findings: 3 main types of attachment
66% Secure attachment
22% Insecure avoidant
12% Insecure resistant
Secure:
caregiver is a secure base - willing to explore
high stranger anxiety
moderate levels of distress when separated from caregiver
obvious joy when reunited with caregiver
Insecure avoidant:
willing to explore
no/little stranger anxiety
indifference when mother leaves the room
ignores or avoids mother during reunion
Insecure resistant:
little willingness to explore
extreme stranger anxiety
intense distress when separated
hard to sooth, seeks and rejects contact during reunion
Secure attachment: 'ideal type'
strong attachment of an infant to their caregiver
occurs as a result of sensitive responding by the caregiver to the infant's needs
related to healthy future cognitive and emotional development
Insecure avoidant attachment:
associated with mothers who do not respond to their child's needs
Insecure resistant attachment:
associated with inconsistent parenting
mother sometimes responds to and sometimes ignores the infant
Strength: the study uses a standardised procedure. This means that it can be replicated due to a high level of control and has been successfully carried out in many cultures. This means that it has allowed researchers to compare attachment types across the world.
follow with counterargument - artificial
Limitation: As the strange situation is highly controlled, it means it is an artificial way of assessing attachment. It is carried out in a lab, with caregiver and stranger acting according to a script. This means that the study will not reflect the way in which a caregiver and baby would interact in daily life. This means the study lacks ecological validity.
Limitation: The strange situation is a culture-bound test which is designed for use in a British/American culture. Children and caregivers from different cultures will behave differently in the study. For example, In Japan, mothers usually terminate the study early due to the high distress of the infant as in Japan, mothers and infants are rarely separated. This means that the same method may not be appropriate for use in all cultures due to differing ways of raising children.
